| dc.description.abstract | The main objective of this research was to compare the effectiveness of natural
coagulants with that of a commonly used chemical coagulant in treating leather
wastewater. We aimed to identify a more sustainable and eco-friendly alternative to
chemical coagulants for wastewater treatment in the leather industry.
Corn powder outperformed all other coagulants in TDS removal by 80.89% at a
dosage of 40 mg/L, demonstrating an efficient and potentially eco-friendly alternative
for treating wastewater. Moringa seed and tamarind seed followed closely in their
ability to remove 68.75% and 72.50%, respectively. Neem leaf and PAC showed the
least effectiveness in reducing TDS, with a percentage of 60.98% and 40.89%,
respectively. At a dosage of 40 gm/L, coagulants demonstrate good performance in
reducing TDS.
Neem leaf proved most effective in BOD removal, with a percentage of 91.67% at
a 40 gm/L dosage. At higher dosages, Moringa Oleifera takes the lead in BOD
reduction, followed by polyaluminium chloride (PAC).
Corn powder shows the comparatively best conductivity removal at an 80 gm/L
dosage. Tamarind seed powder, Moringa oleifera seed powder, Neem leaf powder,
and PAC show increasing conductivity.
Tamarind seed powder and Moringa oleifera powder show good performance in
pH adjustment. | en_US |
